Abstract

A process for isolating a conjugated diolefin from a C4- or C5-hydrocarbon mixture containing the diolefin, by single-stage or multi-stage extractive distillation using a selective solvent, wherein the selective solvent is a solvent mixture which comprises (a) from 50 to 99 percent by weight of a selective solvent boiling at from 140 DEG C. to 260 DEG C. and (b) from 1 to 50 percent by weight of an organic solvent boiling at from 45 DEG C. to 125 DEG C.
